1 Intoduction

Hello, I’m Joseph from Morocco.

Inspired by Hans Rosling’s TED Talk, I taught myself data scraping, analysis, and visualization.
This non-academic approach has given me a unique perspective, as reflected in my projects—though it also means I may require a thorough onboarding process to align with team standards.

I’m open to starting as an intern, either full-time or part-time. Regarding time zones, I’m in UTC+1, but I’m flexible and can adjust my schedule to accommodate the team’s needs.

Feel free to reach me at joseph.ergo@proton.me, and to visit my website for more projects josephelhaddad.github.io.

This custom report, generated from processing 1.4 TB of public data locally, aims to explore the workforce dynamics of a company—up to 2020.
Essentially, I am doing research on a company that does research.

2 About the project

The project came to life after realizing that web scraping doesn’t allow deep-level filtering—without consuming too much time.The irony is, this project itself took me about a month, but the final RDB contains more data than I could ever scrape.

The raw data was 1.4 TB in size and holds information previously scraped.
Processing was done on my local machine using Python, Polars, and DuckDB, following this workflow:
- Processed raw data into structured Parquet files using Polars.
- Transformed each Parquet file into mini RDBs using Polars.
- Merged all mini RDBs into one using DuckDB.
- Analyzed and filtered data to fit the current project.
